--- Doc Text *updated* by Cedric Buissart cbuissar@redhat.com --- A heap buffer overread was found in perl's grok_bslash_N() function, which is used in the compilation of Unicode nodes in regular expressions, possibly leading to crash or dump of memory segments via the error output. An attacker able to give maliciously crafted regular expression could look for sensible information in the error message, or crash perl.
